NATIONAL WEATHER SERVICE PEACHTREE CITY GA
743 PM EDT FRI JUL 17 2015

.PREV DISCUSSION... /ISSUED 328 PM EDT FRI JUL 17 2015/

SHORT TERM /TONIGHT THROUGH SATURDAY NIGHT/...

CURRENT RADAR LOOP SHOWS SOME SCATTERED SHOWERS AND ISOLATED
THUNDERSTORMS POPPING UP ACROSS EASTERN AND CENTRAL PORTIONS OF THE
CWA. THESE SHOWERS ARE DEVELOPING A BIT FURTHER NORTH THAN ORIGINALLY
EXPECTED BUT BUT AREAL COVERAGE IS SPOT ON. WE STILL HAVE A DRIER
AIRMASS OVER THE REGION BUT MOISTURE WILL SLOWLY INCREASE THROUGH THE
WEEKEND AS THE MAIN UPPER LEVEL RIDGE RETRIES BACK TO THE WEST.
EXPECTING DIURNALLY DRIVEN ISOLATED TO SCATTERED SHOWERS AND
THUNDERSTORMS ACROSS MORE OF THE AREA TOMORROW WITH THE INCREASED
MOISTURE AND WEAKENING RIDGE. LOOKS LIKE WE ARE GETTING BACK INTO A
MORE SUMMERLIKE PATTERN FOR THIS REGION. TEMPS ALSO EXPECTED TO BE
MAINLY IN THE 90S WITH 80S IN THE MOUNTAINS.

LONG TERM /SUNDAY THROUGH FRIDAY/...

NO SIGNIFICANT CHANGES WERE MADE TO THE LONG TERM FORECAST GRIDS.

LONG TERM FORECAST DISCUSSION BELOW.

PREVIOUS LONG TERM DISCUSSION /SATURDAY NIGHT THROUGH THURSDAY/...

THE UPPER LEVEL RIDGING SHIFTS WEST THROUGH THE WEEKEND...BRINGING
A NW FLOW ACROSS THE AREA BY EARLY TUESDAY. THIS ALLOWS A WEAKENING
SURFACE FRONT TO DRIFT SOUTHWARD. PROXIMITY OF THE SURFACE BOUNDARY
WILL BRING AN INCREASED CHANCE OF DIURNALLY DRIVEN SHOWERS AND
THUNDERSTORMS THROUGH THE END OF THE WEEK...HOWEVER INCREASE WILL BE
NOMINAL AT BEST. GUIDANCE IS CONSISTENT SHOWING MID 90S FOR AFTERNOON
HIGHS THROUGH THE EXTENDED PERIODS.
